Channel pathway

The Heart channel originates in the Heart, descends through the diaphragm to connect with the Small Intestine. A branch ascends from the Heart to the esophagus, then crosses the face to the eye. Another branch emerges from the Heart, passes through the lung, and descends to emerge in the axilla (HT1). It then travels along the medial aspect of the upper arm, elbow, and forearm, reaching the pisiform bone at the wrist. From there, it follows the radial side of the palm and the medial aspect of the little finger, terminating at its tip (HT9).
